LVS Series Engineering Attributes:

RESISTANCE & TOLERANCES
Select any Ohmic value (Ω) or decimal part of an Ohm from .001Ω to 100KΩ with micro-ohm/micro-volt accuracies to ±.005%. See Figure #2 shown below for the minimum resistance vs. tolerance requirements. PRC's unique single-joint design on the four (4) terminal parts make tab identification academic.
TCR CHARACTERISTICS
0±15 PPM/°C is the standard for this part type. Add LTC in the part name for a lower TCR of 0±10 PPM/°C. This Low Temperature Coefficient (LTC) is only sustainable if the combined temperature of self-heating and ambient (surrounding environment) operating temperature does not exceed +150°C. Please specify temp. span of operation.
STABILITY VS. TIME
To ±.001%/yr. @ 25°C. with no load.
PRECISION POWER
Min. Res. @ Max Watts is based upon ±1% resistance tolerances @ +25°C. Derating is required for higher temperatures, closer tolerances & lower resistance values. See Figure #3 shown below for derating requirements.
PROTECTIVE SEAL
Rectangular solvent-resistant epoxy case is solder heat resistant & offers excellent thermal transfer to base.
TERMINALS
Solderable hot-tinned pure copper (ETP/OFHC) tab terminals & low EMF construction reduces thermal effects usually associated with low value resistors.
MARKING
PRC stamp, part type & name, Ω value & tolerance, physical size permitting.
 
Type LVS Derating Table*
 
For ±1% resistance tolerance apply up to 100% of rated power to +25 Degrees Celsius. derated to zero @ +275 Degrees Celsius.

For ±½% (0.5%) resistance tolerance apply up to 80% of rated power to +25 Degrees Celsius. derated to zero @ +225 Degrees Celsius.

For ±¼% (.25%) resistance tolerance apply up to 60% of rated power to +25 Degrees Celsius. derated to zero @ +175 Degrees Celsius.

For ±1/10% (0.1%) resistance tolerance apply up to 50% of rated power to +25 Degrees Celsius. derated to zero @ +150 Degrees Celsius.

For ±1/20% (0.05%) resistance tolerance apply up to 40% of rated power to +25 Degrees Celsius. derated to zero @ +125 Degrees Celsius.

For ±1/50% (0.02%) resistance tolerance apply up to 30% of rated power to +25 Degrees Celsius. derated to zero @ +100 Degrees Celsius.

For ±1/100% (0.01%) resistance tolerance apply up to 20% of rated power to +25 Degrees Celsius. derated to zero @ +75 Degrees Celsius.

For ±1/200% (0.005%) resistance tolerance apply up to 10% of rated power to +25 Degrees Celsius. derated to zero @ +50 Degrees Celsius.
